Solution

avatarin used GPT-Realtime to build the Kurashi-Marugoto AI Agent for Yamada Denki, creating a 24/7 shopping assistant that can speak, listen, and reason over product information in one loop. The system combines low-latency voice interaction with a retrieval-augmented generation layer so shoppers can ask open-ended questions about needs, space constraints, or budget and still receive grounded product guidance. avatarin also translated Yamada Denki's category-specific sales expertise into prompts and conversation flows, allowing the agent to ask follow-up questions rather than waiting for exact keywords. Guardrails keep the interaction centered on shopping outcomes even when customers change direction, and OpenAI worked with the team on prompt structure, cost optimization, and implementation practices for always-on service. The result is a branded retail interface that preserves context across voice and text while capturing the intent signals conventional ecommerce channels often miss.

Data flow

A shopper speaks or types into the Kurashi-Marugoto AI Agent, which uses GPT-Realtime plus a retrieval-augmented generation layer to combine intent, product data, and Yamada Denki sales patterns into guided recommendations. Voice surveys at the end of conversations feed back customer reactions and intent signals for future improvement.
